请参阅我对这个问题的回答，以了解如何用更少的代码行完成它。这个方法允许你以任何你喜欢的方式动画一个新视图控制器的伪“Push”，当动画完成时，它就像你使用标准的Push方法一样设置导航控制器。我的示例允许您从左边或从右边对滑入进行动画操作。 为了方便起见，这里重复了代码:

-(void) showVC:(UIViewController *) nextVC rightToLeft:(BOOL) rightToLeft {
    [self addChildViewController:neighbor];
    CGRect offscreenFrame = self.view.frame;
    if(rightToLeft) {
        offscreenFrame.origin.x = offscreenFrame.size.width * -1.0;
    } else if(direction == MyClimbDirectionRight) {
        offscreenFrame.origin.x = offscreenFrame.size.width;
    }
    [[neighbor view] setFrame:offscreenFrame];
    [self.view addSubview:[neighbor view]];
    [neighbor didMoveToParentViewController:self];
    [UIView animateWithDuration:0.5 animations:^{
        [[neighbor view] setFrame:self.view.frame];
    } completion:^(BOOL finished){
        [neighbor willMoveToParentViewController:nil];
        [neighbor.view removeFromSuperview];
        [neighbor removeFromParentViewController];
        [[self navigationController] pushViewController:neighbor animated:NO];
        NSMutableArray *newStack = [[[self navigationController] viewControllers] mutableCopy];
        [newStack removeObjectAtIndex:1]; //self, just below top
        [[self navigationController] setViewControllers:newStack];
    }];
}

基于jordanperry为swift 4更新的答案

用于推送UIViewController

let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "yourViewController") as! yourViewController
    UIView.animate(withDuration: 0.75, animations: {() -> Void in
    UIView.setAnimationCurve(.easeInOut)
    self.navigationController?.pushViewController(terms, animated: true)
    UIView.setAnimationTransition(.flipFromRight, for: (self.navigationController?.view)!, cache: false)
})

为流行

UIView.animate(withDuration: 0.75, animations: {() -> Void in
    UIView.setAnimationCurve(.easeInOut)
    UIView.setAnimationTransition(.flipFromLeft, for: (self.navigationController?.view)!, cache: false)
})
navigationController?.popViewController(animated: false)

从示例应用程序中，可以看到这种变化。 https://github.com/mpospese/MPFoldTransition/

#pragma mark - UINavigationController(MPFoldTransition)

@implementation UINavigationController(MPFoldTransition)

//- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
- (void)pushViewController:(UIViewController *)viewController foldStyle:(MPFoldStyle)style
{
    [MPFoldTransition transitionFromViewController:[self visibleViewController] 
                                  toViewController:viewController 
                                          duration:[MPFoldTransition defaultDuration]  
                                             style:style 
                                        completion:^(BOOL finished) {
                                            [self pushViewController:viewController animated:NO];
                                        }
     ];
}

- (UIViewController *)popViewControllerWithFoldStyle:(MPFoldStyle)style
{
    UIViewController *toController = [[self viewControllers] objectAtIndex:[[self viewControllers] count] - 2];

    [MPFoldTransition transitionFromViewController:[self visibleViewController] 
                                  toViewController:toController 
                                          duration:[MPFoldTransition defaultDuration] 
                                             style:style
                                        completion:^(BOOL finished) {
                                            [self popViewControllerAnimated:NO];
                                        }
     ];

    return toController;
}

@Luca Davanzo的答案在Swift 4.2

public extension UINavigationController {

    /**
     Pop current view controller to previous view controller.

     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func pop(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.popViewController(animated: false)
    }

    /**
     Push a new view controller on the view controllers's stack.

     - parameter vc:       view controller to push.
     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func push(viewController vc: UIViewController, transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.pushViewController(vc, animated: false)
    }

    private func addTransition(transitionType type: CATransitionType = .fade, duration: CFTimeInterval = 0.3) {
        let transition = CATransition()
        transition.duration = duration
        transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
        transition.type = type
        self.view.layer.add(transition, forKey: nil)
    }

}

如何改变一个基于导航的应用程序的推送和弹出动画…

如果你是iOS开发新手。对于最简单、最常见的动画(如“滑动”或“一个推另一个”)，你必须做大量的工作。

1. 你需要一个自定义的uiviewcontrolleranimatedtransiting

You need popStyle boolean - is it popping on, or popping off? You must include transitionDuration (trivial) and the main call, animateTransition You must write the two different animations routines, one for the push, and one for the pop. Inside animateTransition, simply branch on the boolean popStyle to one the two routines The example below does a simple move-over/move-off In your animatePush and animatePop routines. You must get the "from view" and the "to view". (How to do that, is shown in the code example.) and you must addSubview for the new "to" view. and you must call completeTransition at the end of your anime

复制粘贴…

  class SimpleOver: NSObject, UIViewControllerAnimatedTransitioning {
        
        var popStyle: Bool = false
        
        func transitionDuration(
            using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
            return 0.20
        }
        
        func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
            
            if popStyle {
                
                animatePop(using: transitionContext)
                return
            }
            
            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
            
            let f = transitionContext.finalFrame(for: tz)
            
            let fOff = f.offsetBy(dx: f.width, dy: 55)
            tz.view.frame = fOff
            
            transitionContext.containerView.insertSubview(tz.view, aboveSubview: fz.view)
            
            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    tz.view.frame = f
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }
        
        func animatePop(using transitionContext: UIViewControllerContextTransitioning) {
            
            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
            
            let f = transitionContext.initialFrame(for: fz)
            let fOffPop = f.offsetBy(dx: f.width, dy: 55)
            
            transitionContext.containerView.insertSubview(tz.view, belowSubview: fz.view)
            
            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    fz.view.frame = fOffPop
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }
    }

然后……

2. 在视图控制器中使用它。

注意:奇怪的是，你只需要在“first”视图控制器中这样做。(在“下面”的那个。)

对于你放在上面的那个，什么都不做。一件容易的事。

所以你的班级…

class SomeScreen: UIViewController {
}

变得……

class FrontScreen: UIViewController,
        UIViewControllerTransitioningDelegate, UINavigationControllerDelegate {
    
    let simpleOver = SimpleOver()
    

    override func viewDidLoad() {
        
        super.viewDidLoad()
        navigationController?.delegate = self
    }

    func navigationController(
        _ navigationController: UINavigationController,
        animationControllerFor operation: UINavigationController.Operation,
        from fromVC: UIViewController,
        to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        
        simpleOver.popStyle = (operation == .pop)
        return simpleOver
    }
}

就是这样。

和平常一样，没有变化。推…

let n = UIStoryboard(name: "nextScreenStoryboardName", bundle: nil)
          .instantiateViewController(withIdentifier: "nextScreenStoryboardID")
          as! NextScreen
navigationController?.pushViewController(n, animated: true)

要弹出它，你可以在下一个屏幕中这样做:

class NextScreen: TotallyOrdinaryUIViewController {
    
    @IBAction func userClickedBackOrDismissOrSomethingLikeThat() {
        
        navigationController?.popViewController(animated: true)
    }
}

唷。

为推动

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:ViewControllerYouWantToPush animated:NO];

为流行

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController popViewControllerAnimated:NO];
